Carlo Ancelotti insists he still has belief in his system as league leaders Chelsea look to end their poor form away from home.

Chelsea have turned Stamford Bridge into a fortress this season, with just one goal conceded since the opening day of the campaign.

In the last three games on their home turf, Chelsea have scored 13 goals without reply – but they are suffering on their travels, where they have lost their last two games.

Defeats at Wigan and Aston Villa temporarily blighted their good start under Ancelotti but victories over Atletico Madrid, Blackburn and Bolton at home have restored confidence in the Italian coach's 'diamond' formation.

Their 4-0 victory over Wanderers on Wednesday night was achieved without numerous first-team regulars.

They will all return against the same opposition tomorrow for a game that will once more test Chelsea's character and Ancelotti's system away from home.
